摘要： An endoscope capable of being autoclaved in accordance with the present invention includes an insertion unit, an internal endoscope space, and contents. The insertion unit has a soft member, which is made of a soft polymeric material, as at least part of a casing thereof. The internal endoscope space includes the internal space of the insertion unit that is formed at a first sealing level at which the internal space is sealed in a watertight manner relative to an outside. The contents include at least one hermetically sealed unit composed of a plurality of airtight partition members and formed at a second sealing level higher than the first sealing level by joining the meeting portions of the airtight partition members using an airtight joining material. All or part of the airtight partition members is stowed in the internal endoscope space. Even when high-pressure high-temperature steam permeates through the soft member of the insertion unit which is made of a polymeric material, and invades into the internal endoscope space formed at the first sealing level, the high-pressure high-temperature steam will be hindered from invading into the hermetically sealed unit included in the contents and formed at the second sealing level.

摘要： An endoscope suitable for autoclave sterilization includes an insertion section having an objective lens section disposed at the extreme end thereof for focusing a subject image and an eyepiece section located on the base end side of the inserting section and including at least an eyepiece lens. an image guide fiber is disposed in the bundle for transmitting the subject image in an observation section focused by the objective lens section. An eyepiece lens unit is disposed in the eyepiece section, the eyepiece lens unit causing the eyepiece lens to confront the base end structure whose hermetic seal level is higher than the watertight seal level of the shell of the endoscope. A focus position changing means is disposed to the eyepiece lens unit to change the focus position of the eyepiece lens. The eyepiece section is so constructed and/or assembled that the autoclave sterilization process does not cause water vapor or the like to adversely affect the operability of the eyepiece section.

摘要： A cover glass frame as a second frame body mounting thereto a cover glass is fitted onto an objective lens frame, which is a first frame body mounting thereto a tip end lens and an objective lens as optical members, in a manner to be movable in a direction of optical axis, and is fixed after having been adjusted in position in the direction of optical axis. The objective lens frame and the cover glass frame thus fitted and fixed are fitted into and joined to a cylindrical member to constitute an imaging unit, which is then arranged in a tip end portion of an insertion part of an endoscope. Thereby, focus adjustment can be performed on the optical members, which are assembled into the imaging unit, and a tip end side portion of the insertion part of the endoscope can be made small in outer diameter to prevent entry of vapor into the imaging unit even when autoclave sterilization is carried out.
